Narrated Mu'adh bin Jabal: "I accompanied the Prophet (ﷺ) on a journey. One day I was near him while we were moving so I said: 'O Messenger of Allah! Inform me about an action by which I will be admitted into Paradise, and which will keep me far from the Fire.' He said: 'You have asked me about something great, but it is easy for whomever Allah makes it easy: Worship Allah and do not associate any partners with Him, establish the Salat, give the Zakat, fast Ramadan and perform Hajj to the HOuse.' Then he said: 'Shall I not guide you to the doors of good? Fasting is a shield, and charity extinguishes sins like water extinguishes fire - and a man's praying in depths of the night.'" He said: "Then he recited: 'Their sides forsake their beds to call upon their Lord.' Until he reached: 'What they used to do.' [32:16-17] Then he said: 'Shall I not inform you about the head of the entire matter, and its pillar, and its hump?' I said: 'Of course O Messenger of Allah! He said: 'The head of the matter is Islam, and its pillar is the Salat, and its hump is Jihad.' Then he said: 'Shall I not inform you about what governs all of that?' I said: 'Of course O Messenger of Allah!'" He (ﷺ) said: "So he grabbed his tongue. He said 'Restrain this.' I said: 'O Prophet of Allah! Will we be taken to account for what we say?' He said: 'May your mother grieve your loss O Mu'adh! Are the people tossed into the Fire upon their faces, or upon their noses, except because of what their tongues have wrought.'"
